Brush Hog Top Link Question

[RoyJackson]

Never experienced it myself, but I've heard that the chains setup can allow the rotary cutter to come waaaaay up to about vertical(?) & about scare the livin' daylights out of ya ... Probably wouldn't happen to often, if ever, so maybe no big deal.

However, if it does I wonder if there's a chance that the chains themselves could actually get caught in the cutter? :shocked:

The real problem is if the cutter came that high, you might have the tail wheel bracket buried in your back or head.
I know some guys do use a chain for the toplink...more power to them. But for me, that toplink provides a limiting factor if the cutter jumps.
I doubt if the chains would be long enough to tangle in the blades though.

If a chain is used in place of a TL, it should be NO longer than the TL was. If that is the case, there is NO chance of it getting caught.

Same for the ones that have the chain from the A-fram down to the tailwheel. Only way it can get caught is if it breaks

This is from the manual on my Land Pride RCR2672


Refer to Figure 2-2:
1. Lower cutter deck to the nominal cutting height.
2. Adjust length of tractor痴 3-point top center link such
that the top and bottom hitch pins are aligned
vertically with each other. The pivot hitch should be
at about a 45 degree angle when adjusted correctly.
3. Lock center link in this position.

It is important to read the manuals.
Per the Land Pride Manual (for an RFM, actually), the hole in the FTB is to be directly above the lower link pins (pictorially, this appears to be the 45 deg angle Triple R refers to).

I'm thinking the chains

Using a chain in place of a toplink is an accident just waiting to happen. I strongly recommend against the practice. Chains between the A-frame and the rear of the mower aren't much better. The purpose of the metal straps is to give the A-frame some flex, while stopping the deck from flipping up and hitting you in the back of the head. Chains instead of straps will in fact give more flex, but do nothing to stop a flipping deck

How is the deck going to magically flip up and hit you in the head??? Are you driving upside down or something???:confused2:

I dunno if it would go quite far enough to hit someone in the head(?), but it could certainly come way up by: Back your rotary cutter into some brush, maybe there's a log in there that the tail wheel goes up & over, then the sides of the deck ride on the log as you continue backing - The further back you go the higher the tail end of the deck rises. I haven't had that happen, but that's the way my dad explained it to me ... when he found out the upper bolt securing the diagonals had come out of the cutter I posted the pick of above.
